Neutrophils are our body's first line of defense against bacterial infections. After leaving nearby blood vessels, these cells recognize chemicals produced by bacteria in a cut or scratch and migrate "toward the smell". In the lab, if neutrophils were placed in a gradient of fMLP (n formyl methionine- leucine- phenylalanine), a peptide chain is produced by some bacteria. The cells charge out like a "posse" after the bad guys. There are no bacteria in this sequence, but if there were, the white cells would eat them by the process of ...
